Bouldin Alfalfa: 2017-03-29 10:00:00 (DOY 88)
Author: Daphne Szutu

Summary: Regular data collection/cleaning, 5 clip plot samples, veg height measurements

2017-03-29
Bouldin Alfalfa

We arrived at 10:00. It was sunny and warm and we could see the snow on the Sierras. The alfalfa is lush and green.

Kyle did 5 clip plot (biomass) samples and measured 20 samples of veg height. Average height was about 40 cm.

Elke cleaned the radiation and EC sensors. We refilled the wash reservoir; it was 4/5 full.

I collected met and USB GHG data and swapped the camera card.

LI7500 readings:
CO2 415.9 umol/mol
H2O 575.4 mmol/m3
T 18.18 Celsius
P 102.1 kPa
SS 106.5 -> 106.8 after cleaning

LI7700 readings:
CH4: 2.11
RSSI: 50.1 -> 75.8 after cleaning

We left at 10:25.

Next Mowing: 2017-04-24
